Abstract

Cognitive radio (CR) has been considered as a promising technology to improve the spectrum utilization. In this paper we analyze the capacity of a CR network with average received interference power constraints. Under the assumptions of uniform node placements and a simple power control scheme, the maximum transmit power of a target CR transmitter is characterized by its cumulative distribution function (CDF). We study two CR scenarios for future applications. The first scenario is called the CR based central access network, which aims at providing broadband access to CR devices. In the second scenario, the so-called CR assisted virtual multiple-input multiple-output (MIMO) network, CR is used to improve the access capability of a cellular system. The uplink ergodic channel capacities of both scenarios are derived and analyzed with an emphasis on understanding the impact of numbers of primary users and CR users on the capacity. Numerical and simulation results suggest that the CR based central access network is more suitable for less-populated rural areas where a relatively low density of primary receivers is expected; while the CR assisted virtual MIMO network performs better in urban environments with a dense population of mobile CR users.

Dynamic <div> Tags

Use JavaScript to make a <div> tag dynamically and then adds code to handle the onmouseclick event to it.": 

/*The following code generates a div in javascript dynamically and add events to it and append it to the
form of html page .*/

// call this function from form of html 
function create_div_dynamic(){

dv = document.createElement('div'); // create dynamically div tag
dv.setAttribute('id',"lyr1");       //give id to it
dv.className="top";                 // set the style classname  
//set the inner styling of the div tag 
dv.style.position="absolute";       
dv.style.pixelLeft=20;
dv.style.pixelTop=100;
dv.style.pixelWidth=10;
dv.style.pixelHeight=20;
dv.style.backgroundColor="red";
//set the html content inside the div tag
dv.innerHTML='<br> hi <br>';

// attach event onmouseclick to the created div tag 
dv.attachEvent("onmouseclick",function(){element_event_onmouseclick();}); 
//finally add the div id to ur form 
document.forms[0].appendChild(dv);

}

function element_event_onmouseclick() //its called for onmouseclick 
{ 
     	alert("Inside function onmouseclick");
   
}
